Abstract

The present invention is an oxygen absorbent which comprises a multilayered body with plural thin resin layers laminated over one another, and at least one laminated side of this multilayered body constructed as an oxygen-absorbing surface; if the surface is not an oxygen-absorbing surface, the surface of the multilayered body is constructed as a gas-impermeable layer. This multilayered body comprises: an oxygen-absorbing layer of a resin composition in which an oxygen-absorbing component is dispersed and which is made as a porous deoxygen layer, a non-porous oxygen-permeable layer, and a porous oxygen-permeable layer as a protection layer for the non-porous oxygen-permeable layer. On at least one side of said oxygen-absorbing layer, one or more of each non-porous oxygen-permeable layers and porous oxygen-permeable layers are combined and laminated over one another; and the respective adjacent layers are thermally bonded to each other.
